如何使用导入Excel更新数据库中的数据。 我正在使用Laravel5.7和Maatwebsite 3.1
这是我的控制器:
public function import()
{
$data = Excel::toArray(new ProdukImport, request()->file('file'));
if ($data) {
DB::table('produk')
->where('id_produk', $data['id'])
->update($data);
}
}
这是我的导入类:
<?php
namespace AppImports;
use AppProduk;
use MaatwebsiteExcelConcernsToModel;
use MaatwebsiteExcelConcernsWithHeadingRow;
class ProdukImport implements ToModel, WithHeadingRow
{
/**
* @param array $row
*
* @return IlluminateDatabaseEloquentModel|null
*/
public function model(array $row)
{
return new Produk([
'id_produk' => $row['id'],
'nama_produk' => $row['produk'],
'harga_jual' => $row['harga']
]);
}
}
此 DD($data) 结果:
array:1 [▼
0 => array:8 [▼
0 => array:3 [▼
"id" => 1.0
"produk" => "Pomade"
"harga" => 90000.0
]
1 => array:3 [▼
"id" => 2.0
"produk" => "Shampoo"
"harga" => 90000.0
]
2 => array:3 [▼
"id" => 3.0
"produk" => "Sikat WC"
"harga" => 90000.0
]
]
]
$data
结果来自:
$data = Excel::toArray(new ProdukImport, request()->file('file'));
根据$data
数组的结构,您可能可以使用这样的东西来实现您想要的:
public function import()
{
$data = Excel::toArray(new ProdukImport, request()->file('file'));
return collect(head($data))
->each(function ($row, $key) {
DB::table('produk')
->where('id_produk', $row['id'])
->update(array_except($row, ['id']));
});
}
我遇到了同样的问题。这是我是如何做到的。
我的控制器如下所示:
public function import(Request $request){
try {
Excel::import(new ProductImport, $request->file('file')->store('temp') );
return redirect()->back()->with('response','Data was imported successfully!');
} catch (Exception $exception){
return redirect()->back()->withErrors(["msq"=>$exception->getMessage()]);
}
}
这是我ProductImport
课上的model
方法
public function model(array $row)
{
$product = new Product();
// row[0] is the ID
$product = $product->find($row[0]);
// if product exists and the value also exists
if ($product and $row[3]){
$product->update([
'price'=>$row[3]
]);
return $product;
}
}
return collect(head($data))
->each(function ($row, $key) {
DB::table('produk')
->where('id_produk', $row['id'])
->update(array_except($row, ['id']));
});
自
return collect(head($data))
->each(function ($row, $key) {
DB::table('produk')
->where('id_produk', $row['id'])
->update(Arr::except($row, ['id']));
});
并使用IlluminateSupportArr;
